I found however that none would really fit the bill, and would need significant kit bashing to fit in the space I had planned for it.
It is at an angle and therefore the building, when viewed from the top would need to be largely triangular. I therefore decided to scratch build my own warehouse. It is entirely 'made up', I don't have a specific prototype for it, but I will make sure it will look 'authentic' enough not to look unrealistic. Besides, I had several scrap bits of styrene laying about that I could use.
Here are some progress pictures. This evening I've spend extending the structure , added a door and steps , re-enforced the inside of the walls and added a ledge on which the roof can be put down, and put a loading floor inside behind the doors. This will enable me to add a small amount of interior details that might be visible where the doors will be modeled open, but not the complete depth of the building.
